The 43-piece switch extension is ideal for connecting multiple tracks. After each ball passes through the switch, it flips, ensuring that subsequent balls always take a different path. This allows builders to decide which ball reaches which target. With this set, a small standalone marble run can be built, or the components can be integrated into a larger marble run.

100% compatible with building blocks from other manufacturers: All Hubelino products fit perfectly with blocks from other well-known brands, thereby optimally complementing the existing collection of building blocks.

Made in Germany for excellent product quality: All Hubelino products are manufactured exclusively in Germany under the highest quality standards.

Learning through play with STEM building sets: Hubelino products focus on a balanced relationship between fun and educational value. Therefore, the development of new products always centers around a learning aspect, which is transformed into a toy with educational benefits through clever design.

The 43-piece switch extension includes numerous track elements, building blocks, a base plate, and balls, with a total of two switches. This set allows for the construction of a small standalone marble run, but the greater fun comes from incorporating the switch as an extension into a larger marble run.

With the modular and compatible marble run, where nothing wobbles or shifts, spatial imagination and basic physical laws are conveyed. Whether with or without building instructions, the colorful setup trains the adherence to sequences, stimulates working memory, and develops analytical thinking skills.
